The plant microbiome is an important factor for health and productivity. While the impact of nitrogen (N) availability growth development well established, its influence on microbial phyllosphere community structure unknown. We hypothesize that impacts abundance several microorganisms leaf surface. bacterial fungal communities baby spinach (Spinacia oleracea), rocket (Diplotaxis tenuifolia) were investigated in a field trial two years commercial setting. Nitrogen fertilizer was tested four...
Ocean acidification (OA) affects the physiology and behaviour of some marine organisms, impacting their development metabolism during vulnerable early-life stages. Among them, embryo cuttlefish develops for about two months in encapsulated eggs with harsh perivitelline conditions hypoxia hypercapnia, potentially worsened by OA. In this study, common Sepia officinalis embryos juveniles, were exposed to five pH (pHT 8.08 7.43). Growth, metabolite profiles explored embryonic period up 10...
The environmental fate and behavior of nanoplastics (NPs) their toxicity against aquatic organisms are under current investigation. In this work, relevant physicochemical characterizations were provided to analyze the ecotoxicological risk NPs in compartment. For purpose, heteroaggregates 50 nm polystyrene nanospheres natural organic matter prepared characterized. kinetic aggregation was assimilated a reaction-limited colloid mode led formation range 100–500 nm. Toxicities these (50 350 nm)...
This work quantified the accumulation efficiencies of Hg in cuttlefish, depending on both organic (MeHg) and inorganic (Hg(II)) forms, under increased pCO2 (1600 μatm). Cuttlefish were fed with live shrimps injected two stable isotopic tracers (Me202Hg 199Hg(II)), which allowed for simultaneous quantification internal accumulation, Hg(II) methylation, MeHg demethylation rates different organs. Results showed that had no impact bioaccumulation organotropism, did not influence microbiota...
Lately, behavioral ecotoxicology has flourished because of increasing standardization analyses endpoints like movement. However, research tends to focus on a few model species, which limits possibilities extrapolating and predicting toxicological effects adverse outcomes at the population ecosystem level. In this regard, it is recommended assess critical species-specific responses in taxa playing key roles trophic food webs, such as cephalopods. These latter, known masters camouflage,...
Due to their various properties as polymeric materials, plastics have been produced, used and ultimately discharged into the environment. Although some studies shown negative impacts on marine environment, effects of freshwater organisms are still poorly studied, while they could be widely in contact with this pollution. The current work aimed better elucidate impact toxicity mechanisms two kinds commercial functionalized nanoplastics, i.e., carboxylated polystyrene microspheres of,...
